Module Overview

Name: Novell ZENworks Configuration Management Preboot Service Remote File Access
Module: auxiliary/scanner/misc/zenworks_preboot_fileaccess
Source code: modules/auxiliary/scanner/misc/zenworks_preboot_fileaccess.rb
Disclosure date: -
Last modification time: 2022-01-23 15:28:32 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): 998
List of CVEs: CVE-2012-2215

This module exploits a directory traversal in the ZENworks Configuration Management. The vulnerability exists in the Preboot service and can be triggered by sending a specially crafted PROXY_CMD_FTP_FILE (opcode 0x21) packet to the 998/TCP port. This module has been successfully tested on Novell ZENworks Configuration Management 10 SP2 and SP3 over Windows.

Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage

This module is a scanner module, and is capable of testing against multiple hosts.

msf > use auxiliary/scanner/misc/zenworks_preboot_fileaccess
msf auxiliary(zenworks_preboot_fileaccess) > show options
    ... show and set options ...
msf auxiliary(zenworks_preboot_fileaccess) > set RHOSTS ip-range
msf auxiliary(zenworks_preboot_fileaccess) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(zenworks_preboot_fileaccess) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(zenworks_preboot_fileaccess) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(zenworks_preboot_fileaccess) > set RHOSTS file:/tmp/ip_list.txt

Required Options

  • RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
